Students will review:
This chapter helps students review the concepts in a chemical reactions, acids and bases unit of a standard GED science course. Topics covered include:
- Water properties
- Components of solutions, including solutes and solvents
- Osmosis, diffusion and saturation processes
- Measurements of acids and bases on a pH scale
- Methods for writing and balancing chemical reactions
- Redox reactions and common chemical reactions
1. Properties of Water
Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.
2. Solutions, Solutes, and Solvents
Oh no! Your friend Ben just drank chili oil on a dare, and now his mouth is burning. Should he drink the ice water or vegetable oil to cool his mouth? Quick. Watch this lesson if you aren't sure.
3. Osmosis, Diffusion and Saturation
The cells in our bodies are in constant flux through the processes of osmosis and diffusion. Learn about how saturation levels force change, and why we're lucky they do.
4. Acids and Bases
Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.
5. How to Write and Balance Chemical Reactions
Halloween glo sticks, firecrackers, table salt and the transport of CO2 waste in the body - what do they all have in common? They are all made possible by chemical reactions.
6. Common Chemical Reactions and Energy Change
This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.
7. Redox (Oxidation-Reduction) Reactions: Definitions and Examples
This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.
8. Acidic Solutions: Properties & Examples
Acidic solutions are found everywhere in the natural world and are an important part of our everyday lives. This lesson defines acidic solutions and discusses their fundamental properties. Several examples of acidic solutions from the natural world and industry are also provided.
9. Arrhenius Acid: Definition & Examples
A scientist named Svante Arrhenius defined an acid as a compound that increases the proton (H+) concentration in a solution. This definition of an acid is what we now call an Arrhenius acid, which is the main focus of this lesson.
10. Buffer System in Chemistry: Definition & Overview
In many ways, our lives are dependent on functioning buffer systems. Learn the definition of a buffer system, understand how it works and assess your knowledge with a quiz.
11. Chemical Reaction Catalyst: Rates & Overview
Catalysts are common in both industrial processes and in the human body. This lesson will explain how they work and why we need them. A quiz will test our knowledge.
12. Closed System in Chemistry: Definition & Example
This lesson provides a basic definition of a closed system from thermodynamics. Examples are included to provide students with illustrations of closed systems that are encountered within chemistry.
13. Combination Reaction: Definition & Examples
There many types of chemical reactions. In a combination reaction, you can predict the product if you know what goes into it. Find out more about combination reactions and see some examples.
14. What is Sodium Bicarbonate? - Structure, Formula & Uses
Have you experienced heartburn? Do you like cooking and baking? Have you encountered stubborn stains? If you answered yes to any of these, then sodium bicarbonate is your friend. In this lesson, we will discuss sodium bicarbonate and its many uses.
15. What Does Chemical Mean in Science?
In this lesson we will learn what a chemical is, how it is defined in science, and the importance of chemicals to our life. We will also learn how society views chemicals versus the definition in science.
